Δεν έμεινε λίθος επί λίθου(The phrase is taken from Matt. 24:2, There shall not be left here one stone upon another) Said for major disasters

Δεν έμεινε ρουθούνι(roughly, "not even a nostril has been left")Said in major natural disasters or wars, when a large number of people or other living creatures have perished. In the major Byzantine-Arab conflict of 11th c, Byzantine historian George Cedrenus describes how after a victorious battle for the Byzantines, general Georgios Maniaces ordered his troops to cut off the ears and noses from the Arab dead and send them to Constantinople as a gift for the Emperor. In Byzantine Greek: "τὰς ῥῖνας καὶ τὰ ὦτα τῶν πεσόντων ἀποτεμὼν" ("he cut off the noses and ears of the fallen")
